correct and easy installation.
The modular cascade frame consists of a number of supports
with connecting frames which are screwed together during
installation.
The compact dimensions of the individual cascade frame parts
enable simple and quick installation.

Items supplied with unit 2
Buderus supplies cascade systems in TL and TR
configurations:
TL: Inline installation
All boiler assemblies are in a line enabling an easy-to-monitor
installation in a narrow room.
TR: Back-to-back installation
The boiler assemblies are located on both sides of the frame
and are installed back-to-back to create a compact installation
which ideally suits rectangular rooms and which ensures the
best possible access to all boilers.
The relevant configuration can be selected on the basis of the
performance required (see table 1).
Boiler assembly connection kit
The connection kit can be used both for the Logamax plus
GB162-80 and for the 100-kW version. The connection kit
includes a pressure relief valve, a non-return valve, a pump
and isolating valves.
Bend sets with low loss header
The Logamax plus GB162 cascade system can be installed in
various configurations (fig. 4). By using the bend set the low
loss header can be installed at an angle to the boilers. The gas
pipe is reversible so that the gas connection can be at the other
side of the boilers to the flow and return connections to the
header.

Cascade frame installation4
4 Cascade frame installation
z Fix the frame onto the first leg of the cascade unit.
Use the M8 x 70 screws for this.
z Now fix the next leg and continue fitting until the cascade
unit is compelte.
z Position the frame into its final position.
z Adjust the frame so that it is in the right position and so that
it is level both horizontally and vertically. Fit additional
washers under the leg until level.
z Secure the frame to the floor. Ensure bolts are aligned to the
legs. Do not bend or place the leg under stress to make it fit.
z Install the main gas pipe. Use the M8 x 70 screws for this.
Do not fully tighten the screws yet.
z Install the header pipe. Use the M8 x 70 screws for this.
Do not fully tighten the screws yet.
z Fit the boiler mounting brackets on the top of the frame.
Install the nuts at the rear of the frame. The underside of the
bracket should be level with the underside of the frame.
Use the M8 x 65 screws for this.
Caution!
Make sure that the surface the cascade
system is to be installed on is flat.
Use a spirit level when installing the cascade
system.
Check that the load-bearing capacity of the
floor is sufficient for the weight of the installa-
tion (approx. 100 kg for each boiler with
accessories).
Caution!
Make sure that the slots for the boiler mounting
bracket are at the top of the frame.
Caution!
For TR-back-to-back configurations, both boiler
mounting brackets are fitted simultaneously,
using the same screws. Only use M8 x 65
screws to secure the mounting brackets.

4.1 Boiler assembly and pump group
installation
z Hang the first boiler on the cascade frame as shown in fig. 7
or fig. 8.
z Put the boiler in the correct position and level it horizontally
and vertically. Use the set screws on the lower rear of the
boiler to adjust it.
z Connect the pump group (see Logamax plus GB162 Instal-
lation and service instructions).
z Remove the protective yellow caps from the main gas pipe.
z Apply PTFE tape to the screw thread connections.
z Connect up the gas connection pipe between the gas valve
and the main gas pipe. Use PTFE tape to create a perfect
seal.
z Remove the protective caps from the header.
z Remove all red paint and unevenness from the flow and
return connections of the header.
z Install the flow pipe(s) between the header and the pump
group.
z Install the return pipe(s) between the header and the pump
group.
z Repeat the above steps to install all boilers.
z If required, seal off any unused connections of the main gas
pipe and the header.
z Install the condensate drain pipe. Use the pre-assembled
mounting brackets on the supports for this.
z When installing a cascade with an angled low loss header,
install the set of bends between the header and the low loss
header. Fit the enclosed flange seals in between. Use the
corresponding screws.
2½" low loss header M12 x 50
3" low loss header M16 x 55
z Install the low loss header with the corresponding flange
seals. Use the corresponding screws.

4.2 Installing the insulation
z Install the rear insulation over the header (fig. 9, item 1).
z When an angled low loss header has been installed, fit the
insulation around the bends.
z Install the rear insulation part over the low loss header
(fig. 9, item 2).
z If required, trim the insulation so that it is straight
(fig. 9, item 3).
z For 2½" and 3" low loss header: install the inserts in the
outer insulation. For a 2½" low loss header: install the redu-
cing inserts in the outer recesses (fig. 10, item 2).
For a 3" low loss header: install the reducing inserts in the
inner groves (fig. 10, item 1).
z Click the insulation together.
z Install the front insulation of the low loss header. If required,
trim the insulation so that it is straight (fig. 9, item 3).
z Install the end cover over the header (fig. 9, item 4).
